Abstract

This invention relates to multi-component fibers made of at least 40 weight percent, and preferably over 50 weight percent of one or more high chain length polyamides. The fibers have both a high tear strength and good tensile strength. The fibers can be used to produce woven and non-woven articles having excellent toughness.
